Monoclonal antibodies against the prototype 8FIIa strain of Norwalk virus
were prepared and applied to an enzyme immunoassay (EIA) for detecting
Norwalk virus in stool specimens. The monoclonal antibodies
immunoprecipitated a 58-kDa protein which had been produced by in vitro
transcription-translation of Norwalk virus cloned cDNA, and they reacted by
EIA with recombinant Norwalk virus capsid protein at a sensitivity level of
1 ng/ml. The EIA detected virus in all tested samples from 15 different
Norwalk virus-infected volunteers. No cross- reactions were seen in stools
containing other caliciviruses or in stools containing rotaviruses,
astroviruses, or enteric adenoviruses.
